Abstract

L'invention concerne un procédé de stabilisation de pente qui permet de placer des boulons de blocage à proximité de positions prédéfinies tout en évitant des arbres, dans le cas où une pluralité de boulons de blocage est placée à intervalles prédéfinis dans une pente naturelle, et des arbres se trouvent en des positions prédéfinies auxquelles les boulons de blocage doivent être placés, lors de la stabilisation de la pente par installation et serrage de plaques d'appui sensiblement triangulaires selon une vue en plan au niveau d'une partie tête desdits boulons de blocage. La position de placement desdits boulons de serrage consiste en une position de placement des boulons de serrage lorsqu'un côté de la forme sensiblement triangulaire desdites plaques d'appui installées au niveau desdites parties tête, est placé à proximité d'arbres selon une orientation faisant face audits arbres. Ainsi, le procédé de l'invention est caractéristique en ce que lesdites plaques d'appui sont installées au niveau des parties tête des boulons de blocage de sorte que ledit côté de la forme sensiblement triangulaire est orienté face audits arbres.
